BACKGROUND Technical Field

The present disclosure relates to transmission methods and devices inwireless communication systems, and in particular to a scheme and deviceof multicarrier transmission in a wireless communication system inwireless communications.

Related Art

Application scenarios of future wireless communication systems arebecoming increasingly diversified, and different application scenarioshave different performance demands on systems. In order to meetdifferent performance requirements of various application scenarios, the3^(rd) Generation Partner Project (3GPP) Radio Access Network (RAN) #72plenary decided to conduct the study of New Radio (NR), or what iscalled fifth Generation (5G). The work Item (WI) of NR was approved atthe 3GPP RAN #75 plenary to standardize the NR.

Enhanced Mobile BroadBand (eMBB), Ultra-reliable and Low LatencyCommunications (URLLC), and massive Machine Type Communications (mMTC)are three major scenarios of application of the NR technology. Andmulticarrier (including Carrier Aggregation (CA) and Dual Connectivity(DC)) is an effective technical means of fulfilling eMBB and URLLCdemands.

SUMMARY

In the multicarrier communications, such as CA, Cross Carrier Schedulingis supported. And in order to meet requirements of URLLC, a UE canmonitor a physical downlink control channel (PDCCH) Candidate based onSpan. A combination of CA and Span-based scheduling can maximize theflexibility of network scheduling and configuration and optimize theentire system's performance.

To address the issue of multicarrier technology application in URLLCscenario, the present disclosure provides a solution. It should be notedthat though the present disclosure only took the multicarrier and URLLCas a typical or exemplary scenario in the statement above, it is alsoapplicable to other scenarios confronting the same difficulty, includingother multicarrier transmissions or multi-channel transmissions, orother networks having specific demands on data scheduling, where similartechnical effects can be achieved. Additionally, the adoption of aunified solution for various scenarios, including but not limited tomulticarrier and URLLC scenarios, contributes to the reduction ofhardcore complexity and costs.

In FIG. 3 , the radio protocolarchitecture for a control plane 300 between a first communication node(UE or gNB) and a second communication node (gNB or UE) is representedby three layers, which are a layer 1, a layer 2 and a layer 3,respectively. The layer 1 (L1) is the lowest layer which performs signalprocessing functions of various PHY layers. The L1 is called PHY 301 inthe present disclosure. The layer 2 (L2) 305 is above the PHY 301, andis in charge of the link between the first communication node and thesecond communication node, or between two UEs via the PHY 301. The L2305 comprises a Medium Access Control (MAC) sublayer 302, a Radio LinkControl (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP)sublayer 304. All the three sublayers terminate at the secondcommunication nodes. The PDCP sublayer 304 provides varied radio bearersand multiplexing between logical channels, and also provides securing bypacket encryption, as well as support for handover of a firstcommunication node between second communication nodes. The RLC sublayer303 provides higher-layer packet segmentation and reassembling,retransmission of a lost packet, and also packet reordering so as tocompensate for disordered reception caused by Hybrid Automatic RepeatRequest (HARQ). The MAC sublayer 302 provides multiplexing of a logicalchannel and a transport channel.

Thecontroller/processor 440 implements the functionality of the L2 layerand layers above. In the DL, the controller/processor 440 providesheader compression, encryption, packet segmentation and reordering,multiplexing between a logical channel and a transport channel and radioresource allocation of the first node 450 based on various priorities.The controller/processor 440 is also in charge of HARQ operation, aretransmission of a lost packet and a signaling to the first node 450,for instance, the higher-layer information contained in a firstinformation block, a fourth information block and a fifth informationblock of the present disclosure is generated in the controller/processor440. The transmitting processor 415 performs various signal processingfunctions used for the L1 layer (i.e., PHY), such as coding,interleaving, scrambling, modulation and power control/allocation,precoding and physical layer control signaling generation. For example,the generation of physical layer signals of a first information block, afourth information block and a fifth information block of the presentdisclosure is completed in the transmitting processor 415. When there isat least one among the M1 control channel candidates in the presentdisclosure being used for transmitting a control signaling, thegeneration of the control signaling transmitted is completed in thetransmitting processor 415. Modulation symbols generated are dividedinto parallel streams and each stream is mapped onto a correspondingmulticarrier subcarrier and/or multicarrier symbol, and is then mappedby the transmitting processor 415 to the antenna 420 via the transmitter416 and transmitted in the form of a radio frequency signal. At thereceiver side, each receiver 456 recovers baseband informationmodulation onto a radio frequency carrier and provides the basebandinformation to the receiving processor 452. The receiving processor 452provides various signal receiving processing functions of the L1. Thefunctions include receiving physical layer signals of the firstinformation block, the fourth information block and the fifthinformation block in the present disclosure and monitoring the M1control channel candidates in the present disclosure, as well asmodulating based on each modulation scheme (e.g., BPSK,) throughmulticarrier symbols in the multicarrier symbol streams, and alsode-scrambling, decoding and de-interleaving to recover data or a controlsignal transmitted by the second node 410 on a physical channel, andthen provides the data and control signal to the controller/processor490.

The controller/processor 490 is alsoresponsible for HARQ operation, retransmission of a lost packet, and asignaling to the second node 410. The second information block and thethird information block in the present disclosure are generated in thecontroller/processor 490. The transmitting processor 455 performsvarious signal transmitting processing functions used for the L1 (thatis, PHY), and physical layer signals of the second information block andthe third information block are generated by the transmitting processor455. Signal transmitting processing functions include sequencegeneration (for signals generated by a sequence), coding andinterleaving to ensure Forward Error Correction (FEC) at the UE 450 andmodulation on baseband signals (for signals generated by a bit block)based on various modulation schemes. Signals generated by a sequence ormodulation symbols are later divided into parallel streams and each ismapped to a corresponding multicarrier subcarrier and/or a multicarriersymbol, and then is mapped by the transmitting processor 455 to theantenna 460 via the transmitter 456 to be transmitted in the form of aradio frequency signal. The receiver 416 receives the radio frequencysignal via a corresponding antenna 420. Each receiver 416 recoversbaseband information modulated on a radio frequency carrier and providesthe baseband information to the receiving processor 412. The receivingprocessor 412 provides various signal receiving processing functions forthe L1, including receiving a physical layer signal carrying the secondinformation block and the third information block of the presentdisclosure. The functions also include acquiring a multicarrier symbolstream, performing demodulation of multicarrier symbols comprised in themulticarrier symbol stream related to sequence-unpacking or based onmodulation schemes (such as BPSK, QPSK), decoding and de-interleaving ofthe demodulated symbols to recover data and/or a control signaloriginally transmitted by the first node 450 on a physical channel.Afterwards, the data and/or control signal is provided to thecontroller/processor 440. The controller/processor 440 implements the L2functionality, including reading the second information block and thethird information block in the present disclosure.
